`heap_caps_malloc` 函数允许你为分配的内存块指定一组能力(capabilities)。这些能力定义了该内存块可以执行的操作,例如读、写、执行等。这使得内存分配具有更高的安全性和灵活性。 函数的原型通常如下: ```c void* heap_caps_malloc(size_t size, uint64_t capabilities); ``` 参数解释: 1. `size`:要分...
pBuffer = heap_caps_malloc(Data_Length + 1, MALLOC_CAP_SPIRAM); if (pBuffer == NULL) { DEBUG_LOGE(UART, TAG,"Memory Allocation failed\n"); return NULL; } else { DEBUG_LOGD(UART, TAG,"*** bytes allocated via heap_caps_malloc %d address is =%p", Data_Length,pBuffer); } ...
void*buf3 = heap_caps_malloc(screenWidth * screenHeight, MALLOC_CAP_DMA);if(buf3 ==NULL) { Serial.printf("data is %d", buf3); } produces this output: Code:Select all datais0 vritzka Posts:29 Joined:Wed Sep 07, 2022 5:33 am ...
void*heap_caps_malloc(size_tsize,uint32_tcaps ){returnNULL; } Is this function deprecated? what is flash_mock.cpp? In the heap_caps.c I have also found the real heap_caps_malloc function declaration: Code:Select all IRAM_ATTRvoid*heap_caps_malloc(size_tsize,uint32_tcaps){void* ptr...
void *heap_caps_malloc(size_t size, uint32_t caps); /** * @brief Free memory previously allocated via heap_caps_malloc() or heap_caps_realloc(). * * Equivalent semantics to libc free(), for capability-aware memory. * * In IDF, ``free(p)`` is equivalent t...

We also use malloc to test the allocation of internal ram and psram, and the same error occurs, and the malloc API will not be fully executed to the last return line; the error has already started to be reported directly inside the call to malloc() or heap_caps_malloc(). The detailed...
2. **使用内存分析工具**：使用 ESP-IDF 的内存分析工具，如 `esp_heap_caps_dump()` 和 `esp_...
